Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a walk-behind rice transplanter with a fertilizer application device, which has a fertilizer hopper with a feeding roll installed at left and right positions above the bonnet, which has a spare seedling loading section formed on the top surface. .

[Prior art]

In this type of walk-behind rice transplanter with fertilization device,
Conventionally, the fertilizer hopper was located on the outermost side of the machine to avoid interference with the propulsion wheels that move up and down in accordance with the plowing depth, and the fertilizer hopper was positioned as far inside the machine as possible. A feed-out roll drive arm that is rod-linked to the planting mechanism and swings back and forth is installed on the inner side of the feed-out roll. (Reference not shown) [Problem to be solved by the invention] However, since the roll drive arm is located on the inner side of the feed roll, the preliminary seedlings and the drive arm are arranged in close proximity. As a result, there was a risk that the spare seedlings would come into contact with the swinging drive arm and be damaged.

The purpose of this invention is to make simple changes to the drive arm so that the fertilizer hopper is moved as much as possible to the inside of the machine, while making it difficult to have a negative impact on the on-board spare seedlings and making it easy to adjust the amount of fertilizer delivered. The goal is to be able to place it at a high level and at a low level.

[Means for solving problems]

In order to achieve the purpose of the walk-behind rice transplanter with a fertilization device according to the present invention, in the above-mentioned one, a knob for adjusting the amount of feeding is provided on the outer side of the feeding roll, and A roll drive arm that is rod-linked to the planting mechanism and swings back and forth is installed at a location located directly above the spare seedling loading section on the inside, and the swing range of the roll drive arm is set at a high position above the arm fulcrum. The functions and effects are as follows.

[Effect]

Even if the fertilizer hopper is located as low as possible inside the fuselage to prevent or suppress an increase in the width or height of the entire aircraft due to the fertilizer hopper, and Even if the adjustment knob is arranged so that the knob for adjusting the feeding amount is located on the outer side of the feeding roll so that it can be easily operated, as a result, the roll drive arm is placed directly above the spare seedling loading section. Even though it is equipped, the range of swing of the roll drive arm is at a higher position than the arm fulcrum, making it easier to avoid contact between the roll drive arm and the spare seedlings to be mounted.

[Effect of idea]

Therefore, by simply modifying the swing range of the roll drive arm, the fertilizer hopper can be placed as close to the inside of the machine as possible and at a low level.
The entire aircraft can now be made compact and easy to handle in terms of both width and height.

Moreover, the amount of fertilizer applied can now be adjusted easily and efficiently by easily operating the feeding amount adjustment knob.

In comparison, the spare seedlings are mounted in such a way that they are less likely to be damaged by the roll drive arm, making it possible to plant the seedlings in a state where they are less likely to suffer from poor growth after planting.

〔Example〕

As shown in FIG. 4, an engine 2 is attached and fixed to a frame 1 provided at the front of the aircraft, and a transmission case 3 is provided behind the engine 1. At the rear end of the planting transmission case 4, which also serves as a frame and is arranged toward the front and back, there is a planting mechanism 5, a seedling stand 6, and
The aircraft with the handle 7 installed is the mission case 3
A pair of left and right propulsion wheels 9, 9 pivotally supported at the lower ends of transmission cases 8, 8 swingably mounted on both sides of the
A front float 10 is provided at the intermediate front part of the propulsion wheels 9, 9.
a, and a walking type in which seedlings are planted one after another while supporting the field at an appropriate height through cooperation with a float group consisting of a pair of left and right rear floats 10b, 10b arranged behind the propulsion wheels 9, 9; Configure the rice transplanter.

As shown in FIGS. 2 and 3, a bonnet 11 is provided to cover the engine 2 and the transmission case 3, and a recessed portion capable of storing one stage of spare seedlings is formed on the upper rear surface of the bonnet 11. The reinforcing frame 12 installed between the stays 14, which will be described later on the fertilizer hopper 16, and the upper surface of the bonnet 11 are configured so that the second tier of spare seedlings can be placed thereon. A possible spare seedling loading section 13 is formed.

Fertilizer hoppers 16, 16 with left and right feeding rolls 15 are fixed to stays 14, 14 set up from the fulcrum P of the bonnet 11, and a drive shaft 17 passing through the left and right feeding rolls 15, 15 is installed. With respect to the drive shaft 17, the roll drive arm 18, which is rod-coupled with the swinging arm 5A of the planting mechanism 5, is placed at a position on the lateral inner side of the feeding roll 15 and directly above the preliminary seedling mounting section 13. The fertilizer is fitted so as to be rotatable as a unit, and the appropriate fertilizer is delivered to a predetermined position via the downstream hose 19 and the furrower 20 by the reciprocating swing of the roll drive arm 18 that is linked to the planting mechanism 5. A possible fertilizer application device has been constructed.

As shown in FIG. 5, below the discharge port of the fertilizer hopper 16, a stationary delivery roll 15A having a fertilizer receiving recess 15a is fitted onto the drive shaft 17 so as not to be movable in the axial direction thereof. With,
A movable delivery roll 15B having a receiving recess 15a and a protrusion 15b that can be engaged and disengaged is attached to the fixed sleeve 2 with respect to the fixed delivery roll 15A.
1, and is fixed to the outer end of the stationary sleeve 21 and protrudes outward from the sides of the fuselage.
Due to the rotational action of the fertilizer receiving recess 15a, the receiving space of the fertilizer receiving recess 15a is configured to be variable, thereby making it possible to vary the amount of fertilizer delivered.

As shown in FIG. 1, the swinging range of the roll drive arm 18 is set to a position higher than the arm fulcrum X to the drive shaft 17, and the arm 18 is brought into contact with a preliminary seedling located below the drive shaft 17. It is intended to avoid this and minimize the impact on reserve seedlings.
